Horseshoe-calking vise



`NITED STATES PATENT OFFICE.,

FORD B. CURTIS, OF GARDINER, MAINE.

HORSESHOE-CALKING VISE.

Speeilicat-ion forming part of Let-ters Patent No. 49,388, dated August 15, 1865.

To all whom it may concern:

Be it known that I, FORD B. CURTIS, of Gardiner, in the county ot' Kennebec and State of Maine, have invented a new and useful HorseshoeUalking Vise or Machine; and I do hereby declare the same to be fully described in the following speciiication and represented in the accompanying drawings, of which- Figure 1 is a top View, Fig. 2 a front elevation, and Fig. 3 a vertical section, of it. Fig. 4 is a front elevation of it with a horseshoe arranged with it.

In the said drawings, A is a stationaryjaw ixed to the side of a post, D, and projecting upward therefrom, as shown in Fig. 3.

B is a movablejaw to operate with` the stationary jaw A, there being a spring, G, between the two for moving the movablejaw in a direction away from the other jaw. At its lower end the said movable jaw is hinged to the head or screw D, which screws into the -post D-that is, the head of the screw extends into the lower part of the jaw B, and has a pin, b, passed through it and the jaw. By withdrawing the pin from the jaw and the screw and separating them from one anotherthe screw will be lei't free to be turned around, so as to move its pin-hole either farther from or nearer to the post, the saine beingl to enable the inner face ot' the movablejaw to be adj usted to the proper distances and inclinations relatively to `the fixed jaw for horseshoes of different thick` nesses.

A screw, E, provided with a hand-lever, F, goes through the movable jaw a-nd screws into the stationary jaw, or into it and the post, and serves to clamp the jaws on a horseshoe when placed between them, in manner as shown in Fig. 4.

'lhe clamping parts of both jaws should be made so as not only to be capable of firmly grasping a shoe when between them, but of permitting the heels thereof and their calks to project beyond thejaws or out ot' them, in manner as shown in Fig. 4.

The upper end ofthe movable jaw is scart'ed down or sloped toward the fixed jaw, or is rerlhe npperjaw, A, projects above thejaw B and has an arched top, the same being not only to enable a smith to impart to the calk the requisite curve to correspond with that of the toe ofthe shoe, but to prevent the blows of the hammer on the calk during the process of swaging itfrom causing the calk to spread out on the upper face ofthe shoe. Thus the construction of the jaw A saves the lnecessity of tiling down the shoe at the top surface 0f the toe after formation ofthe calk. i

The object of the recess or slope c is to enable a blacksmith to impart to a calk, while projecting from a shoe, its proper wed ge shape, or, in other words, to sharpen it when dull. To accomplish this he places the shoe between the jaws so that the calk may rest on the inclined surface c. Next, with a hammer he beats down the calk to a sharp edge, such calk, while being so sharpened, being in a heated state.

A heel-ca`lk ot'a shoe maybe similarly treated, arranging'the shoe in the machine inthe manner as represented in part by dotted lines inV Fig. 1i. f

I do not claim a horseshoe-calkn g vise made as represented in Letters Patent No. 34,786, as my vise is not formed for the reception and holding of any movabledies.

What I claim as my invention is- The horseshoe-calking vise constructed wit the calli-forming recess or slope c in one of its jaws, and having its otherjaw extending above such recess and arched, substantially as and for the purpose specified.

, F. B. CURTIS.
